chiitel, Switzerland, have invented certain new and useful Improvementsin and Relot ing to iYl'tfiilifll'COIilbUStiOn Engines, of which tucioilowing is o. specification.

The present invention hasfor its object an internal cmnbustion enginehaving two cylinders and being particularly applicable for use. on motorcycles nnd motor-road vehicles generally.

The ncconipzuiying drawing shows by way of example a constructional formof motor in accordance with the present invention.

Figure l is a. sectional view through A.B of Fig. .2. Fig 2 is n frontview in which the valve-boxes are shown in section; the cover of the boxcontaining the valve driving device being removed. Fig; .3 is anexterior view of the said cover. Fig. 4 is an interior view of the someshowing the valve driving devices. 'Eig. 5 is an interior and Fig. 6 anexterior view of the device carrying the elec tricnl contracts oi theiiring means.

The motor sl'iown in the drawing has two cylinders a radially arrangedon the casing l) in such o. manner that the geometric axes of thecylinders are situated in alineinent reletivoly to a plane passing er)endiculerly through the driving shaft. do of the cylindersns well astheir relntive distributing devices are symmetrical as regards a. lonepassing through the axis ot the drivings raft;

the inlet and outletvslves ofthe two cylin dei-s being arranged inplanes similar to the arranged in pairs on stationery bolts. Each of thetwo pistons c is connected by s rod d yith c bolt e connecting the artsof the onble ily-wheel f. The rods zi nre ivoted on bolts 5; within thepistons c. he fiywheel f which is mounted in the casing b, transmits itsrotary movement to the drivingshait h of the motor on one side and ontheother to a shaft i provided with a pinion Z: actuating, s toothedwheel 1 fixed on a shaft 0 and/meshing with another toothedi wheel mfixed on e'sha tt o.
